Three balaclava-clad men armed with hammers and bats smashed their way into a Banbury home before attacking and hospitalising the victim asleep inside.
Police said the men bashed their way through the front door of the home in Merton Street to get in, before carrying out a ‘brutal attack’ on the 31-year-old man.
The man was asleep in bed when he was assaulted by the trio shortly after midnight on April 8.
Officers said the intruders then fled and the victim stumbled out of his home to alert neighbours.
The victim was treated at the Horton General Hospital for a head injury.
Investigating officer Detective Constable Bryan Groves of Force CID at Banbury said: “This was a brutal attack in the victim’s own home.
“It has left him feeling very frightened for his safety.”
